Tomikawa Jurô joined the Shinsengumi in 1865. He protested against becoming a Bakufu retainer because it went against his Sonnô ideology. He tried to join the Goryô Eji but was refused by Itô Kashitarô. He then asked Aizu han for permission to leave the Shinsengumi but was also refused. He and other 3 members, Ibaraki Tsukasa, Sano Shimenosuke, and Nakamura Gorô commited Seppuku.
His gravesite confirms this, stating that he committed suicide on 6/14/1867, however other sources state that he was actually killed by Ôishi Kuwajirô and others.
